well i have one of these and read the comments
 i did mine a different way
took off the lid
then looked all around  
there is  a white plastic lump inside the casing directly behind the  door handle 
i disconnected power and  fiddled around with this  from the top
 you reach just past it and there is a part that moves lift this up  around the 3 oclock position viewed from front of machine it comes up about qtr or half an  inch and the door pops 
just put a wash on after coming back from greece (door jammed when sister stayed house sitting and used machine and will see if it opens or i have to rig a string or something and  drill a hole in the lid so i can open it that way in future. cheers
